Core Tip

Core Tip: Gastric linitis plastica (GLP) is a form of gastric cancer that is difficult to diagnose by an endoscopic biopsy. An ultrasonography-guided fine-needle biopsy is useful for diagnosing GLP with negative endoscopic biopsy findings. Meanwhile, autoimmune pancreatitis (AIP) is an immunoglobulin-G4 related disease (IgG4-RD) that occasionally coexists with gastric cancer. Some cases of IgG4-RD have been reported to be improved by the treatment of malignant tumors, suggesting that IgG4-RD may develop as a paraneoplastic syndrome. From the clinical course and image findings, we experienced a suspected case of AIP developed as paraneoplastic syndrome coexisting with GLP.
